When you first begin to exercise, it’s somewhat painful. Not wildly painful, like touching a hot stove, but enough that if your only goal was to avoid pain, you certainly would stop doing it.

Yesterday Twitter announced that they plan to amend the assignments agreements that they sign with their employees. They call this proposed amendment the Innovator's Patent Agreement. I've been aware of this effort inside of Twitter for a while and I like to call this move the "Twitter Patent Hack" because I think…
Yesterday I encountered a blog whose comment section wasn’t linked up with Facebook or Disqus. It was just a pure email/display name system from years past – one where no one had any interest in tracking your activity across the entire interwebs.

About a year ago I built a Chrome extension called SiteChat -- the premise was simple: turn every website into a chatroom. The app was an instant success, and over the following year I watched entire societies emerge and die off inside the bizarre ecosystem that I had created. Genesis and
Since I had one week before my next contract I decided to finish my "cycle of id". After Doom , Doom Iphone , Quake1 , Quake2 , Wolfenstein iPhone and Doom3 I decided to read the last codebase I did not review yet: idTech3 the 3D engine that powers Quake III and Quake Live .

In the late 70s, a beggar outside Harvard Square station asked for a quarter to take the subway. I gave him one. As I walked down the stairs I noticed that he was not coming along.
